Technical field
The invention belongs to imflammable gas safe transport technical field, relate to a kind of ceramic core spark arrester, using the medium that Extruded Monolithic Celluar Ceramics is propagated in pipeline as blocking-up flame, the safety in emergency circumstances guaranteeing spark arrester opposite side pipeline, equipment can caught fire in spark arrester one side ducts.Compare with existing spark arrester, have that volume is little, windage is little, corrosion-resistant, easy care and low cost and other advantages.
Background technology
The woven wire that conventional spark arrester adopts multilayer fine and closely woven is as back-fire relief medium.When flame runs into the fine and closely woven woven wire of multilayer, because woven wire makes chemical reaction extinguishing to the cooling effect of flame instantaneously, thus reach the object stoping flame to be propagated in pipeline.Although conventional woven wire spark arrester can effectively stop flame to be propagated in pipeline, the following problem of ubiquity: the silk screen 1, using multilayer fine and closely woven, gas channel is irregular, resistance is large, causes system fan power consumption larger; 2, for suitably to reduce windage, strengthen actual internal area and cause again spark arrester volume to increase later, requirements of installation space is larger; 3, wire Netease is corroded by dust, steam, air-flow, causes windage to increase further after woven wire corrosion, slagging scorification, even disappears because heat transfer deterioration back-fire relief function weakens simultaneously; 4, woven wire is once corrosion or stained, cannot keep in repair, and can only change whole spark arrester; 5, woven wire is not easily processed, expensive.
Summary of the invention
For overcoming the above-mentioned shortcoming and defect of existing spark arrester function, structure, the object of the invention is to: a kind of ceramic core spark arrester is provided, using the medium that Extruded Monolithic Celluar Ceramics is propagated in pipeline as blocking-up flame, the safety in emergency circumstances guaranteeing spark arrester opposite side pipeline, equipment can caught fire in spark arrester one side ducts.Compare with existing spark arrester, ceramic core spark arrester be fast using heat transfer rate, Extruded Monolithic Celluar Ceramics that thermal capacity is large as back-fire relief medium, have that volume is little, windage is little, corrosion-resistant, easy care and a low cost and other advantages.
The technical scheme that the present invention takes for its technical problem of solution is:
A kind of ceramic core spark arrester, comprise the inlet flange, entrance straight length, expansion segment, back-fire relief section, contraction section, outlet straight length and the outlet(discharge) flange that set gradually from air-flow upstream to downstream, it is characterized in that: in described back-fire relief section, laminating arranges ceramic honey comb core body, described ceramic honey comb core body is closely combined by one or more ceramic honey comb monomer to form, and described ceramic honey comb core body is being 100mm ~ 300mm along the melt flow length L in air current flow direction.
Further, the housing of described expansion segment and contraction section is respectively equipped with a watch window.
Further, the housing upper of described back-fire relief section or sidepiece are provided with a maintenance window, and described maintenance window is flexibly connected with described back-fire relief piece housing.
Preferably, described ceramic honey comb monomer comprises the ceramic thin-walled of " well " word shape and foursquare gas channel, and the inscribed circle diameter a of described foursquare gas channel is 0.6mm ~ 2mm, and the thickness b of described ceramic thin-walled is 0.3mm ~ 1mm.
Preferably, described ceramic honey comb monomer comprises the ceramic thin-walled of honeycomb shape and hexagonal gas channel, and the inscribed circle diameter a of described hexagonal gas channel is 0.6mm ~ 3mm, and the thickness b of described ceramic thin-walled 11 is 0.3mm ~ 1mm.
Innovative point of the present invention is: 1, use the medium that Extruded Monolithic Celluar Ceramics is propagated in pipeline as blocking-up flame, utilize the feature instantaneous cooling flame that ceramic honey comb heat transfer rate is fast, thermal capacity is large to make chemical reaction extinguishing, thus reach the object stoping flame to be propagated in pipeline; 2, watch window is set, is convenient to observe operation conditions, maintenance window is set, be convenient to change ceramic honey comb.
Compare with traditional spark arrester, the invention has the advantages that: 1, use the medium that Extruded Monolithic Celluar Ceramics is propagated as blocking-up flame in pipeline, back-fire relief is effective, and gas-flow resistance is little, and spark arrester volume is little; 2, Extruded Monolithic Celluar Ceramics stable chemical nature, can be used under dust, steam and fluid media (medium) have certain corrosive environment; 3, ceramic honey comb be widely used, low price, be easy to buying.4, spark arrester arranges maintenance window, can clear up, changes after ceramic honey comb is stained, maintenance, easy to maintenance.
